Techno-economic Analysis on Ground-source and Air-source Heat Pump Systems

摘要

In this study, a comparison has been made on ground-source heat pump (GSHP) with air-source heat pump (ASHP). Two main categories of GSHPs (horizontal and vertical) are analyzed technically and economically. Monthly heating/cooling capacities and coefficients of performance for air-source and vertical and horizontal ground-source systems are calculated. The desired type of heat exchanger is determined by considering economic factors such as the total cost, comprised of the capital and operating costs. The cost-effectiveness of investments of each system is discussed, with parameters, such as the payback period. It is concluded that the GSHPs offer better techno-economic viability.
